DataBinding: How to set BindingContext?

Hey guys,

I have following JSON:

"customers": [

{

  "name": "Meyer",

  "first_name": "Hans",

  "order" : [

  {

  "article_number" :"123456",

  "description" :"Deo"

  }

  ]

},

I want to set the BindingContext for my control with this method:

setBindingContext(oContext, sName?)

How can i create object oContext?

I tried following, but its not working:

var oModel = this.getView().getModel("ModelKundenInfos");

var sPath = "/customers/0";

var context2 = {oModel : oModel, sPath : sPath};

Thanks + regards

Chris
